Abstract : The designer/developer of fault tolerant avionics must consider the requirements to validate these digital systems. These requirements should be primary factors influencing the design and hence the sustainability of these systems. This paper presents a synopsis of a methodology of design and validation of digital avionics and flight control systems based upon early consideration of validation requirements. Avionics developed using this methodology will provide real time fault detection and isolation and hence reduce aircraft down time due to avionics failures. Changes in mission requirements will be reflected in the need to modify or add software modules throughout the system's life cycle. This necessitates design and control of hardware and software interfaces in order to keep the time required to validate the change to a minimum and speed retrofit of the modification in the operational units.
